Top Security Researchers Ask The Guardian To Retract Its WhatsApp Backdoor Report (technosociology.org)

Earlier this month The Guardian reported what it called a "backdoor" in WhatsApp, a Facebook-owned instant messaging app. Some security researchers were quick to call out The Guardian for what they concluded was irresponsible journalism and misleading story. Now, a group of over three dozen security researchers including Matthew Green and Bruce Schneier (as well as some from companies such as Google, Mozilla, Cloudflare, and EFF) have signed a long editorial post, pointing out where The Guardian's report fell short, and also asking the publication to retract the story. From the story: The WhatsApp behavior described is not a backdoor, but a defensible user-interface trade-off. A debate on this trade-off is fine, but calling this a "loophole" or a "backdoor" is not productive or accurate. The threat is remote, quite limited in scope, applicability (requiring a server or phone number compromise) and stealthiness (users who have the setting enabled still see a warning; "even if after the fact). The fact that warnings exist means that such attacks would almost certainly be quickly detected by security-aware users. This limits this method. Telling people to switch away from WhatsApp is very concretely endangering people. Signal is not an option for many people. These concerns are concrete, and my alarm is from observing what's actually been happening since the publication of this story and years of experience in these areas. You never should have reported on such a crucial issue without interviewing a wide range of experts. The vaccine metaphor is apt: you effectively ran a "vaccines can kill you" story without interviewing doctors, and your defense seems to be, "but vaccines do kill people [through extremely rare side effects]."

    Why the heck would they retract the truth?
    If your threat model includes government spying, WhatsApp is not secure since the government can force WhatsApp to reissue your key and then scoop us the resulting messages.
    The editorial spin on this story from slashdot is very disappointing.

    WhatsApp is big money...and combined with the fact it's hard to prove that a vulnerability was intentional and thus a "back door" it's hard for Joe Average to tell who's right.

    Don't worry about this stuff. Just keep using WhatsApp. It's just as secure as everything else, honest.

    Telling people not to use WhatsApp is apparently "endangering people"...as it is a "crucial issue".

    Summary; do not use Signal, ChatSecure, OTR or Telegram. Use WhatsApp, it's clearly safer #because_danger (??).


    Personally I never thought WhatsApp was secure even after this (maybe backdoor-ed) end to end encryption - Consider many people use WhatsApp? it's the number one target IM. If it ever was secure it won't be so tomorrow.

    Read the article. The people they are concerned about are journalists and activists in repressive countries who use WhatsApp because it provides encrypted messaging. If they switch to Signal, which almost no one uses, just being observed using it may be enough cause for the government to pick them up. If they are able to use WhatsApp, however, they are hiding among the millions of other people that use it for no special reason other than it is a good messaging app.

    What are you even talking about. A bunch of people that signed the editorial are academic cryptographers who work for universities. What big business are you talking about now? Mozilla is the biggest business represented in the list, do we hate them now too? The EFF? Do we hate them? I can't keep up with things around here.

    Yes, but even in the area of science you'll notice that who says something still has some meaning.

    If I say that at the center of every black hole there is a little pink teapot, you'll call me a crackpot and be done with it.
    If Stephen Hawking made this claim, I bet you would want to know his reasoning.

    At the very least this meant for me that I would want to see why Bruce considers it a non-issue.
